Seneca the Younger 225
Roman Stoic philosopher, statesman, and dramatist -4–65 BCRelated quotes

“When asked what learning was the most necessary, he said, "Not to unlearn what you have learned."”
Antisthenes, 4.
The Lives and Opinions of Eminent Philosophers (c. 200 A.D.), Book 6: The Cynics

“The most useful piece of learning for the uses of life is to unlearn what is untrue.”
“All the lessons learned, unlearned”
"Fall of a City"
Selected Poems (1941)
Context: All the lessons learned, unlearned;
The young, who learned to read, now blind
Their eyes with an archaic film;
The peasant relapses to a stumbling tune
Following the donkey`s bray;
These only remember to forget. But somewhere some word presses
On the high door of a skull and in some corner
Of an irrefrangible eye
Some old man memory jumps to a child
— Spark from the days of energy.
And the child hoards it like a bitter toy.
